1) They'd already made a head start with The Vanishings:
x2 trailers and a 'series announcement' no less, set in their own home, performed solely by N and Maddie, filmed and edited by M. What was the barrier to continuing with the project?
Episodes dropping from the 1st March 2019! (M's promise, not mine.)
2) They'd already done a photo shoot for their vow renewal:
They could have planned that.
3) One day they started a film project in the lounge where M play a pilot or something and the girls made sound effects. It was
tit.
4) One day M started rewriting the lyrics to something for N to 'perform'. They gave up. It was
tit.
Sorry but I can't be bothered to search for the evidence of 3 and 4 - It's all
tit.
It's impossible to cheer on
YTubers who can't be bothered.
The YTubers you've mentioned
NotJustMeThen sound inspirational. M has a panic attack at the mention of putting up a shelf.
